Let's divide 503691 by 79
The aim is to understand the frequency of 79 in 503691.

Going ahead to step 1:
The number 79 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 79

Advancing to step 2:
50 divided by 79 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 79

Advancing to step 3:
503 divided by 79 is 6 with a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 474 away from 503, we end up with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 79

Step 4:
296 divided by 79 is 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtracting 237 from 296 leaves us with 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 79

On to step 5:
If we divide 599 by 79, we get 7 and a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 637.0
Deduct 553 from 599 and we're left with 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 79

Moving on to step 6:
461 divided by 79 is 5 with a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 6375.0
If we subtract 395 from 461, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
If we divide 660 by 79, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 6375.8
Subtracting 632 from 660 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
The number 79 fits into 280 3 times, leaving a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 6375.83
The remainder is 43 after subtracting 237 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
79 goes into 430 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 6375.835
Subtracting 395 from 430 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
350 divided by 79 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 6375.8354
The remainder is 34 after subtracting 316 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
The number 79 fits into 340 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 6375.83544
Deduct 316 from 340 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 6375.83544, with a leftover of 2.4e-05.
